Compound words combine two smaller words to create a new word with its own meaning. Learning to recognize and decode compound words is a powerful reading strategy—once students see that “sunflower” is just “sun” + “flower,” longer words become much less intimidating.
What Are Compound Words?
A compound word is formed when two words join together to make a new word. The meaning of the compound often comes from combining the meanings of both parts: a “sunflower” is a flower that follows the sun, and a “rainbow” is a bow (arc) of colors that can appear after rain when sunlight shines through moisture in the air.
Three Types of Compound Words
Compound words come in three forms. Most compound words students encounter in elementary grades are closed compounds, but understanding all three types helps with spelling and reading.
Two words joined with no space—the most common type.
Two words joined with a hyphen—common in adjectives and some nouns.
Two words that stay separate but work as one concept.
How These Lists Are Organized
Students learn compound words in predictable stages. Younger learners do best with words they can picture easily, while older students can handle more abstract or academic compounds. That’s why the lists are divided into grade bands:
- K–2: Concrete, highly familiar words (usually closed compounds) that are easy to visualize and “break apart.”
- 3–5: A wider mix of everyday and school vocabulary, including some open compounds students see in reading and content areas.
- 6–8: More abstract, academic, and technical compounds, with more hyphenated and open forms common in informational texts.
These are typical grade ranges—students vary, so teachers can use the lists for differentiation and review.

More Compound Words
Additional compound words that don’t fit neatly into other categories.
A note on historical compounds: Some common words like into, upon, without, within, and cannot began as compounds long ago, but today they function as prepositions, conjunctions, or contractions. They’re usually taught as high-frequency sight words rather than as compound word examples.

Frequently Asked Questions About Compound Words
What is a compound word?
A compound word is formed when two or more words join together to create a new word with its own meaning. For example, “sun” + “flower” = “sunflower.” The meaning of the compound often comes from combining the meanings of both parts.
What are the three types of compound words?
The three types are: closed compounds (written as one word, like “sunflower”), hyphenated compounds (joined with a hyphen, like “well-known”), and open compounds (written as two words but functioning as one concept, like “ice cream”).
How do I know if a compound word is closed, hyphenated, or open?
There’s no single rule—it depends on usage and convention. Closed compounds are most common for established words. Hyphenated compounds often appear before nouns (“well-known author”) or for clarity. Open compounds are common for newer combinations. When in doubt, check a dictionary.
Why are compound words important for reading?
Recognizing compound words helps students decode longer words by breaking them into familiar parts. When a child sees “sunflower,” knowing it’s “sun” + “flower” makes it easier to read and understand than treating it as one long unfamiliar word.
When do kids learn compound words?
Children typically begin learning simple compound words in kindergarten and first grade (like “cupcake” and “rainbow”). More complex compounds, including hyphenated and open compounds, are introduced in upper elementary and middle school.
Can compound words be more than two words?
Yes! Some compound words combine three or more words, like “mother-in-law” or “merry-go-round.” These are less common but follow the same principle—multiple words working together as a single concept.
